Abstract: A method, program, computer program, system for obtaining multiple lenses from one single semi-finished lens, and to corresponding lenses; steps are foreseen for obtaining lens specification information, and generating, on the basis of the lens specification information, integrated surface data including lens surface data and junction surface data. The lens surface data includes data representing at least one surface for each of the at least two lens units; the junction surface data includes data representing at least one junction surface joining respective surfaces of the at least two lens units. The integrated surface data represents a physical surface that is to be obtained by machining one single semi-finished lens.

Abstract: A method for designing, by means of a computer, at least one surface of a lens for a user. The method includes the steps of (i) obtaining displacement information on an amount of displacement between a user specific fitting position and a reference position, the reference position representing a primary fitting point of a lens surface on a reference line of sight of an eye of the user, and the user specific fitting position representing a user specific fitting point of the lens surface determined on the basis of the user; and (ii) causing calculating a design of the at least one surface of the lens on the basis of said displacement information.

Abstract: Provided is a block device that mounts a lens shape processing lens holder to a convex surface of a spectacle lens with two alignment reference marks for identifying a distance portion design reference point on a concave surface. The block device includes an imaging unit that images the alignment reference marks of the spectacle lens supported by a support unit from a convex surface side of the spectacle lens, an information processing unit that obtains expected imaged positions of the alignment reference marks imaged by the imaging unit, using information regarding the spectacle lens, when a posture of the spectacle lens supported by the support unit becomes a reference posture suitable for mounting the lens holder, and a display control unit that displays images of index marks indicating the expected imaged positions obtained in the information processing unit and images of the alignment reference marks.

Abstract: A pair of right and left spectacle lenses each includes: a distance vision region and a near vision region; and a progressive region in which a refractive power progressively changes between the distance vision region and the near vision region. In the pair of right and left spectacle lenses mounted in a spectacle frame, a height position of a distance eye point that is a reference point of the distance vision region is different between right and left, and a corridor length connecting the distance vision region and the near vision region is different between right and left.
